Cosmic event... The sun will be exactly between Earth and Mars. Source: Supplied
A RARE space event will happen this week when Mars will be exactly opposite the sun to the Earth.
The cosmic alignment, known as an opposition, will take place on Wednesday (April 8).
On the day of opposition, Mars, Earth and the sun fall on a straight line.
While Mars' orbit of the sun is more elliptical (oval-shaped) than the Earth's, our planet is closer to the sun, meaning it completes its orbit in 365 days, compared to 687 days for Mars.
These differences mean an opposition is rare, occurring about once every couple of years.
